前面有网友提问“不定式作表语时如何翻译”时，摘录了2022新高考全国卷1的阅读B的一个段落：

Like most of us, I try to be mindful of food that goes to waste. The arugula (芝麻菜) was to make a nice green salad, rounding out a roast chicken dinner. But I ended up working late. Then friends called with a dinner invitation. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even worse, I had unthinkingly bought way too much; I could have made six salads with what I threw out.

我这里请想问的是：这里的 way too 是什么用法？
